1958 ; Matsushima, 1975 ). Kramasamuha sibikaSubram. & Vittal has erect con idiophores whichdevelop in small fascicles from a common base andwhich may elongate sympodially. The ampuIliformcells are usually arranged in whorls . The conidiadevelop singly on narrow stalks, are ellipsoidal,z-septate, with the apical cells distinctly paler thanthe thick-walled central cell (Subramanian &Vittal, 1973; Matsushima, 1975).

The above-mentioned genera are related to eachother and also to the other genera with basauxicconidiogenesis, e.g. Arthrinium Kunze, CordeliaSpeg., Dictyoarthinium Hughes and Papularia Fr.They without doubt represent a phylogenetic entityof dematiaceous hyphomycetes with pigmented,often oblate or bilaterally flattened conidia. Septain the conidia or in the conidiogenous hyphae oftenshow dark incrustations. Most of the species growon litter of monocotyledons, especially of grassesand palms. Their teleomorphs belong to genera ofthe Sphaeriales, e.g. Physalospora Niessl andApiospora Sacco

The author thanks Dr K. A. Seifert and DrO. Constantinescu for reading the manuscript andfor useful comments. Dr. G. S. de Hoog confirmedthe identification of the species.

Three new species of Mycovellosiella, M. desmodiicola, M . malvacearum and M . trijugae aredescribed. They cause leaf spot diseases on Desmodium pulchellum, Kydia calycina andSchleichera trijuga respectively.

During the collection of plant pathogenic fungi onforest vegetation of the terai belt of northeasternUttar Pradesh, three foliicolous fungi were collectedin February 1979. Following detailed studies it isconcluded that they are undescribed taxa. Descrip-tions and illustrations follow.

Lesions amphigenous. Colonies hypophyllous,mostly angular, vein-limited, discrete, small, moreor less cottony, olivaceous brown; myceliummostly superficial or partly immersed, repenthyphae sometimes intertwined to form loosecord-like structures, narrow, 1'5-3'0 pm diam,light brown, septate, smooth; stroma absent.Conidiophores solitary, macro- to semimacronema-tous, mononematous, pale olivaceous brown,cylindrical, erect, more or less flexuous, aseptateand small to rarely septate and large, profuselybranched or unbranched, geniculate with distinctcicatrized scars, 4-46 x 3'5 pm. Conidiogenous cellsintegrated, terminal becoming intercalary, poly-blastic, sympodial, olivaceous brown with subhya-line to hyaline apices, loci cicatrized. Conidiasolitary to catenate, a few ramoconidia also present,dry, obclavate, mostly with subacute to rarelyobtuse apices, obconicotruncate bases, pale oli-vaceous brown, smooth, transversely 2-8-septate,basal scar cicatrized, 18'5-76'0 x 2'5-4'0 pm.

After comparing the type collection with descrip-tions of species already described (Shaw &Deighton, 1970; Katsuki, 1973; Sutton, 1973;Deighton, 1974, 1979; Brown & Morgan-Jones,1977; Kumar & Kamal, 1981, 1982; Yen, 1981;Rai, Kamal & Singh, 1982) it shows slight

resemblance only to M. cajani (P. Henn.) Rangelex Trotter known on Cajanus cajan but also foundon other Leguminosae and M. sublateritia (P.Henn.) Deighton known only from Vernonia sp. ofthe Compositae (Deighton, 1974) in colour ofconidiophores and conidia. However, M. desmodi-icola differs from these two species in size ofconidiophores, shape, size and number of septa inconidia and in the symptoms it causes'.

Details of this species have been compared withthose of described species of Mycooellosiella (Shaw& Deighton, 1970; Katsuki, 1973; Sutton, 1973;Deighton, 1974, 1979; Brown & Morgan-Jones,1977; Kumar & Kamal, 1981, 1982; Yen, 1981; Raiet al., 1982) and none will accommodate thisspecies. No species of Mycovellosiella has beenreported to occur on this host genus.

Lesions hypophyllous. Colonies hypophyllous,more or less discrete in the beginning butcoalescing to become somewhat effuse, dark grey toblackish, mycelium mostly superficial or partlyimmersed, repent hyphae narrow, l'5-3'5 pmdiam, interrwining to form loose cord-like struc-tures, pale olivaceous brown, septate, smooth;stroma absent. Conidiophores mostly solitary,macro- to semimacronematous, mononematous,olivaceous brown, cylindrical, erect, more or lessflexuous, septate, smooth, unbranched to rarelybranched, geniculate with distinct conidial scars,14-69 x 3 '5-6'0 pm. Conidiogenous cells integrated,terminal, becoming intercalary, polyblastic, sym-podial, cicatrized, light brown, apices almosthyaline, conidial scars distinct. Conidia mostlycatenate, ramoconidia also present, simple, dry,acropleurogenous, oblong-cylindric, obtuse at theapices, more or less obconicotruncate at the bases,olivaceous brown, smooth or slightly constricted atthe septa; commonly 1-10 transversely septate(occasionally more) with distinct scars at thebases and other points of attachment if any,16-84 x 3 '5-6'5 pm.

Mycovellosiella trijugae has been compared withthe descriptions ofknown species of Mycovellosiella(Shaw & Deighton, 1970; Katsuki, 1973 ; Sutton,1973; Deighton, 1974, 1979 ; Brown & Morgan-Jones, 1977; Kumar & Kamal, 1981, 1982; Yen,1981; Rai et al., 1982). It shows some similarity withM. concors (Casp.) Deighton (Deighton , 1974) onSolanum spp. and M. pithecellobii (Mulder) Deigh-ton (Deighton, 1979) only known from Pithecello-bium, in the type of mycelium and colour of conidiaand conidiophores. However, it differs from bothin size of the conidiophores and size and numberofconidial septa. In addition, it also differs from M .concors in having catenate conidia and in the totalabsence of a stroma. No species of Mycovellosiellahas been reported on this host.

The authors wish to express their gratitude to DrP. M . Kirk, C.M.I., Kew for confirming theidentity of the fungi; Dr E. K . Cash, Binghamton,U .S .A . for rendering Latin diagnoses of the newtaxa; the head of the department of Botany,Gorakhpur University, Gorakhpur, India forproviding excellent facilities for this work; and theUniversity Grants Commission, New Delhi forproviding generous financial assistance to the firstauthor.
